Again, fantastic program. I was wondering if anyone has figured out a way to restrict dropping an item in an area. I've implemented the ability to have some items stationary, but I need to figure out how to prevent some items being dropped between specific
items. Whereas I've grouped some elements together, I dont want the user to be able to insert elements inside of this subgroup.
List is 1,2,3,4,5,6,7,8
4,5,6 are connected and move as a group
I dont want to a user to be able to place 8 in between 4 & 5 or 5&6.
